[Handwritten, above text body]: FJH{Fred J. Hardy - Chief Dev. Engineer} [with a tick mark] [Handwritten, to the right]: In due course. On FD.{Frank Dodd - Bodies}273 herewith we shew the strengthened pivot, having a pin equal to that of Wraith 111. [Handwritten]: FJH{Fred J. Hardy - Chief Dev. Engineer} The boss on the yoke will not need increasing on B.111, but it will be necessary to increase it as drawn on the B.50 yoke piece. Opportunity of re-spacing the stud centres of the lower flange has been taken as requested some little while ago to improve the oil seal.
